As indicated above, register 502 is preserved the battery information that has by the determined precision of number of the numerical digit in this field.In order to reduce memory-size, the number of numerical digit is reduced.As a result, this information is stored with given " low precision ".When initialization, for example after battery 103 was connected to electronic equipment 102, electronic equipment 502 read the numerical value that is stored in the field of preserving information needed.In the course of the work, electronic equipment 102 keeps following the tracks of these battery parameters, and this parameter can be upgraded by (internally) and be stored in the form 501 with high accuracy, and low accordingly accurate values can be stored in this battery.Therefore, as long as battery is connected to electronic equipment 102, perhaps this battery can be discerned electronic equipment, and then this electronic equipment is preserved the information of the more detailed battery parameter that is comprised than this battery itself.
The index that is included in the form 502 can (for example be changed by electronic equipment 102, result as current battery capacity), but also can be upgraded by battery information acquiring unit 115, this battery information acquiring unit 115 is for example controlled by a microcontroller 114 in this battery.Do not comprise at battery under the situation of microcontroller, by using communication line 106, battery information acquiring unit 115 can be controlled by the microcontroller in the electronic equipment 102 109.For example, battery information acquiring unit 115 is used to measure the current capacity of battery, and uses measured information to upgrade the content of form 502.
Form shown in note that 502 only comprises the code with three numerical digits, but can use the number of arbitrary number, for example according to the type of wanting stored information.Relation between the form 502 and 503 is a simple one-to-one relationship.
Relation between the form 501 and 503 has many modes, for example the top field in form 502 (it can be relevant with the current capacity of battery) can with the top parameter value of field in this form 501 (PV1, PV4 ..., PV
N-2) relevant, the field in the form 501 is relevant with the field 503 with identical numerical value of given field in form 502.Similarly, and then the field under the top field in form 502 can with field under the parameter value of the top field in form 501 and then (PV2, PV5 ..., PV
N-1) relevant, the field in the form 501 with have form 502 in the field 503 of the identical numerical value of given field be correlated with.
In a preferred embodiment, parameter value PV1-PVn represents the scope of designated parameter value.Therefore, according to the present invention, can avoid rough expression for the complete dynamic range of this parameter.
